It takes some of its power from solar cells connected to a power inverter, which measures the system’s power requirements to regulate how much additional electricity is needed. Operating fully, the PV contributes about 10% of the power, while for background air-conditioning – about 30% capacity – PV contributes 70% of the system’s power requirements.
